More airbox questions

[oneliterbeater]

Does anyone know the size of the two bolts that fasten the airbox to the frame on a 79 GS100L? Mine are missing, and it is shown on the fiche on boulevard, but it doesn't give a number for it, or a description.

Also, while I was messing around the other day trying to sort that out, I had it running and when I would rev it, fuel would come trickling out of the drain hole on the airbox. Do I have stuck floats?

I have tested the petcock and it functions properly as far as I can tell. I have NOT rebuilt the carbs yet. I ordered new carb boot o-rings and hex hardware from Robert Barr, but have not tackled that yet either. I've kind of been waiting until I have all of the pieces of the puzzle to put back together before I tear everything apart. I'm hoping my carb boots are still good.

The bolts are M6 and about 20mm long (plenty of room if they're too long).

And it sounds like you have stuck float(s) or faulty float valve(s) or just incorrectly set float height(s).

Should be 10mm bolts. Try looking at fiches on alpha-sports.com

HampshireHog is right, 6mm by 20mm long (I just bought some two weeks ago).

I guess I haven't messed with metric hardware enough. Are there different thread pitches, or will that be standard?

And thanks for the help so far.

I believe the 6mm only has the one sort of pitch but I'll have to look at mine again when I get home. Sorry.
